POWER-TRANSMISSION DEVICE.

Specification of Letters Patent.

Patented July 23, 1918.

Application filed September 25, 1917. Serial No. 193,154.

To all whom it may concern:

Be it known that 1, BEN SCHMI T, a citizen of the United States,residing at Bigstone City, in the county of Grant and State of SouthDakota, have invented new and useful Improvements in Power-TransmissionDevices, of which the following is a specification.

The invention is an attachment to be applied to motor vehicles and seeksto provide, as its principal object, a device to permit the power of theengine of such a vehicle to be utilized for purposes other than thedriving of the machine.

Another object is to provide such a device which may be attached tovarious makes of motor vehicles without requiring radical modificationsto be made.

Still another object is the provision of a device which will be enabledto accomplish its purpose without detracting from the general appearanceof the vehicle to which it is attached.

Still another object is to provide a device of this kind which is simplein constriiction', which may be easily and cheaply made and which willeffectively accomplish the purpose for which it is designed.

Other and further objects will appear in the detailed description of thedevice which follows.

In illustrating and describing the inven tion, a particular design hasbeen adhered to, to which, however, the invention is to be in no warestricted. The right is claimed to ma c any changes or alterationssuggested by the demands of practice, pro vided such changes oralterations are comprehended in spirit by the subjoined claims.

In the accompanying drawings z Figure 1 is a view partly in section andpartly in elevation, showing the forward end of a conventional form ofauto-vehicle with the invention applied thereto.

Fig.2 is a plan view of the structure shown in Fig. 1. v

Fig. 3 is a collective view, partly in section, showing the ends ofconnectin shafts which form a part of the device.

Referring to the drawings, there is shown the front end of theconventional form of automobile, in which front end the engine 1 ismounted with its shaft 2 projecting forwardly therefrom, this shaftbeing provided at its end with a well'known clutch member 3. Engagingthe clutch member 3 there is a mating clutch member 1 and this lattermember isattached to the rear end of the shaft 5. This shaft 5 is thatto which the starting crank would be attached, were not the presentinvention applied to this particular machine; and the shaft is equippedat its forward end with an integral extension 6 which is square in crosssection and whose diagonal width is less than the diameter of the shaft.The shaft is provided with a. mnventional bearing 7 in the vehicle framebelow the radiator S and is capable of longitudinal movement as well asrotary movement in this hea ring, so that, when the shaft 5 is used forstarting the engine, it may move forward disconnecting the clutchmembers i and 8 after the engine has been started. This longitudinalmovement of the shaft 5 is precluded, however, when the present deviceis attached, in order that the shaft 5 may act as a connecting linkbetween the engine and the device.

The forward downwardly curved ends 9 of the vehicle tt'ran'le to whichthe forward ends of the springs 10 connect are intended to be utilizedas a means for supporting the forward end of the device. An angle iron11 is provided of slightly greater length than the distance between theoutsides of the two forward ends 9 of the vehicle frame. This angle ironl'lhas attached to one of its flanges near the ends thereof and by meansof suitable rivets 12 the curved plates 13 which extend at right anglesto the length of the angle iron but which are curved to correspond tothe curved ends 9 of the frame. These plates 13 are off-set with respectto the flange of the angle iron 11 to which they are attached, so thatthis flange may lie in a plane parallel with the plane of the shaft 5.The plates 13 are secured in position on the curved ends 9 of the frameby means of U-bolts 14 which straddle the curved ends 9 of the frame andreceive over their free ends the plates 15 which lie against the upperface of the plates 13, nuts 16 being screwed onto the threaded ends ofthe U-bolts 14 and holding the plates 15 in place. The plates 13 and theangle iron 11 which they support are thus securely attached to theforward curved ends 9 of the vehicle frame.

At the longitudinal center of the angle plate 11 and on the upper facethereof, there is mounted a suitable bearing 17. A

shaft 18 is journaled in this hearing near its forward end and carries acollar 19' which is designed to abut this bearing on i the inner face, aset screw 20 being provided for securing the collar in place on theshaft.

Just in front of the radiator 8 and also connected between the forwardends ofthe vehicle frame, there is, asecond. angle-iron 21, sopositioned that its under face will lie parallel with the shafts 5', and18.. This position brings one flange of this angle iron into ahorizontal plane and. the other flange 1 into a vertical plane, thevertical flange hav- 1 of the shaft 18 is journaled in this secondhearing and this; shaft is provided on this rear end with a broachedhole 25, square incross section and of proper dimensions to receive thesquare shaped extension 6 of the shaft 5. I

The shaft 18 is, equipped at its forward end on that part which projectsfromcthe bearing 17 with pulleys '26and 27, the pulley 27 being fixed tothe shaft and the pulley 26 being provided with a flange and looselymounted on the shaft. 7

From the drawings and the foregoing description,'it will be easilyunderstood how the device is attached and the embodiment disclosed showshow the device may be utilized without removing the shaft which receivesthe starting crank. -With the clutch members 3 and 4 in engagement, theshafts 5 and 18 coupled by means of the square extension 6 and thesquare hole25 and the collar 19 positioned against the inner face of thebearing 17, the longitudinal movement of the shafts5 and 18 is precludedand the rotary movement of the engine isthus transmitted to the pulley27 from which a belt may be carried to any device which it is desired tooperate by the engine. The loose pulley 28 provides means for stoppingas desired, without stopping the engine, any

,flopies of thiapatent'may be obtained for Although the invention isillustrated as being applied without doing away with the starting-crankshaft, it is obvious" that this shaft (represented by shaft 5) may beremoved, and the main shaft of the device (represented byshaft 18); maybe extended through the bearing previously occupiedby the starting-crankshaft and receive on. its end a coupling 4 adapted to engage thecoupling 3. If this arrangement is employed the angle iron 21 and thebearing which it supports will be unnecessary, since their place will betaken by the bearing previously occupied by the starting-crank shaft.The manner in which the angle iron 11 is supported and connected to thecurved ends 9 of the vehicle frame enables the position of this angleiron and the bearing which it supports to be varied in position so as tobring this hearing in alinement with the bearing of the starting-crankshaft. Since the plates 13 are held frictionally on the curved ends 9 ofthe vehicle frame by the U-bolts 14, their positions, on these curvedends may be varied, so asto, raise or lower the angle iron 11 with itsbearing 17 thus effecting; the alinement desired.

What is claimed'isz- In a device of the kind set forth, a shaft, aforward bearing therefor, a support for said bearing consisting of anangle iron for transverse positioning across the forward downwardlycurved :ends of an auto vehicle frame, curved plates secured to theangle iron near the ends thereof and at right angles thereto, the platescorresponding to the curvature of the curved ends of the vehicle frame,U-bolts straddling the plates and the curved ends of the frame wherebythe supportas awhole is secured frictionally to the frame to enable itspositioning to aline the shaft with the vehicle engine shaft, means forcoupling the shaft to the vehicle engine shaft, and tight and loosepulleys carried by the shaft.

In testimony whereof I affix my signature.
